BELT AND HUOK UNITER.

Application filed July 26, 1909. Serial No. 509,633."

To all whom it may concern:

Be it known that I, RUnoLF R. -MILAs, a5

citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Belt and Hook Uniters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will en-. able others skilled in the art to-which it appertains to make and use the same.

My invention relates to the construction of that class of devices commonly termed belt clampsywhich are employed for holding the ends of machinery'belting in apposition while permanently securing the same; and hasfor its several objects the provision of means which shall not only retain the belt ends in proper relation but also the fasten-' ing device or devices in proper relation to the belt ends, so as to relieve the operator of the weight of the belting and permit him to freely employ both hands in making the connection, thus dispensing withthe aid of w an assistant and greatly facilitating the operation.

In uniting the ends of machinery belting the old method of lacing has been largely superseded by what are commonly termed hooks, or metallic plates having a series of spurs or projections upon one face which spurs or projections are clenched after being.

forced into the belting. In applying such hooks it is necessary that the operator not only hold the two ends of the belt in proper relation, and the hook in proper relation to the belt ends; but'also an anvil or block beand the employment of ahelper is i't'req uently rendered difiicult or impossible by reason of the location where the work is to be per formed. c

To eliminate the above noted obj ections to the present formof belt clamps, andefl'ect 'the purposes of my invention, I combine witlrclamps for the belt ends an intermediate anvil or bed block to sustain the hook and support it under the clenching blows of -the hammer, and such ,a 1 construction em bodies the main feature of my. invention.

springs 3 which have one bearing on the outer end of the slide'and the other on lugs or projections 1, either formed on or secured to the bed-plate 1. In the present instance the springs 3 have pockets 3 in the slide and the lugs or projections 1' are removably secured to the bed-plate 1 by screws 4*.

The upperv surface of the anvil or bedplate 1' and of the slide 2 are preferably ridged or corrugated as at- &-5, the better to co-act with the clamp levers in holding the belt ends in proper position on the anvil or bed-plate 1. a

6, 6 indicate brackets arranged over the bed-plate 1 and slide 2 parallel to eachother and to the clamp seat (1, 2 and at such a distance above the bed-plate land slide 2 as will accommodate a belt of any desired thickness. These brackets 6, 6 may be formed therefrom. and secured thereto in any suitable manner. Each bracket 6 is slotted longitudinally as at G tor the reception of an adjustable or shifting bearing 7 on which is suitably journaled a cam lever 8, preferably roughened on its cam surface, as at 8, and adapted, when rotated, to clamp the end of a belt to the bed-plate 1.

As the clamp seat (1?, 2 is expansible hooks, it will be noted that by a proper adjustment of the bearings 7 of cam levers 8 provisionmay be-made for different widths of belting, and that whatever the width of belting may be, withina given range, the

of the belt so as to avoid any tendency to lateral displacement or canting of the belt ends. It will also be noted thatthe corrugations 5, 5 of the bedplate and slide also assist in preventing any side twistor canting of the belt ends, andthus aid in sea aring the proper relation tat-belt ends and back at the time the parts are permanently secured together, v

The construction Of the device being substantially such as hereinbefore pointed out, it will be employed as follows for uniting belt ends: The cam lever bearings 7 'will first be adjusted in the slots 6 so as to bring the cam levers 8 to a point which will correspond with the median line of a belt of the width to be operated upon, a belt-hook a of the proper length and Width is then inserted in the clamp seat (1, 2 formed between brackets, and cam levers the operator may employ both hands, but

when the beit ends are secured the operator will be relieved of the weight of the belting and the several parts will be so connected that the operator will beat liberty to employ one hand for steadying the bed-plate 1" and connected parts, and the other for using the hammer in clenching the spurs on the metallic fastener or hook. When the belt ends and hook have been firmly united, the device vmay be readily withdrawn laterally by simply turning the belt. levers 8, 8 so as to release the belt from bed-plate 1.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. In a belt end uniter, the combination of spaced clampmembers forsecuring the ends of the belt in juxtaposition, and a bed plate constituting a support for the fastener below and intermediate of the clamp -memhers.

2. In a belt end uniter, the combination with a bed-plate having a clamp for holding the fastening device, of belt clamps for securing the belt ends inposition over said fastening device.

3. In a beltend uniter, the combination with a bed-plate having ayielding slide clamp, of adjustable belt end clamps carriedby said bed-plate.

I 4. In a beltand hook uniter, the combination with a bed plate, of brackets arranged in parallel relation overthe bed plate, slidahle bearings on said brackets, and cam levers vjournaled on said slidable bearings.

5. In a b'elt end uniter, the combination with a bed-plate having a spring supported cla1np-'slide,.of slotted brackets arranged in parallel relation over the bed plate and slide, slidablejournal blocks on said slotted journaled on the slidable journal blocks. I

6. In a belt end uniter, the combination with clamp members separated by an intervening space and arranged in parallel relation, of a bed plate 'having' a fastener seat intermediate of and below the clamp members.

In testimony whereof I affix mysignature,
